High Borosilicate Tea Cup
High Borosilicate Tea Cup
A high borosilicate tea cup is made of high borosilicate glass. It's primarily composed of silicon dioxide and boron trioxide. It possesses a high degree of heat resistance, withstanding temperature fluctuations ranging from -30°C to 150°C. Laboratory-verified data even indicates a high-temperature resistance range of 300°C to 500°C. This ensures high safety and peace of mind. Even 100°C boiling water at home won't break the glass. Ordinary glass can only withstand temperatures up to 50°C. This is the advantage of high borosilicate glass, ensuring complete peace of mind in everyday life.
The high borosilicate glass tea cup features a double-layered exterior, effectively protecting hands from burns and maintaining the temperature of the drink. Furthermore, the entire high borosilicate glass tea cup boasts an ergonomic design. The rounded rim, repeatedly polished and refined, creates a refined finish that prevents scratches on the lips. The base of our high borosilicate glass tea cup features a thickened, non-slip design and a low coefficient of expansion. Therefore, the bottom of the cup can withstand greater thermal stress. The bottom of an ordinary glass cup experiences much less heat than borosilicate, and is also more susceptible to cracking due to uneven heating. Therefore, for both safety and practicality, borosilicate glass is our top choice.
For first-time users of borosilicate glass teacups, how should we clean them? Below are several methods for your reference.
1. Soaking Method: Place the borosilicate glass teacup in boiling water and wait for 5-10 minutes to soften any dirt clinging to the cup walls. For areas like the bottom of the cup that are more difficult to clean, add a small amount of rice and water and shake vigorously to remove dirt.
2. Detergent Cleaning Method: Prepare a soft-bristled brush and mix warm water with a small amount of dishwashing liquid. After 5 minutes, gently scrub the glass with the brush to avoid scratches. Note: Use a neutral detergent.
3. Stubborn Stains: Mix white vinegar with warm water. After soaking for 30 minutes (depending on the condition), wait for it to soften before wiping with a soft cloth. Finally, wipe with clean water. If there is any odor, treat it with toothpaste.
For borosilicate glass teacups, our top priority is health and safety. Compared to ordinary glass, these do not contain any heavy metals like lead and cadmium. Even with long-term use, they do not release any harmful substances, making them extremely safe to use. They are also very suitable for infants, young children, and the elderly. Furthermore, when cleaning, any coffee, tea, or milk powder stains can be simply rinsed with clean water. This is very convenient and will not leave any odors. Furthermore, we offer a variety of colors and styles to meet the needs of different customers.
How can we distinguish genuine borosilicate glass teacups from fake ones when purchasing? There are usually several ways to check:
1. Listen to the sound. If the sound of a borosilicate glass cup is clear and long-lasting, there's absolutely no problem. If it makes a muffled sound, it's probably ordinary glass. Run!
2. Weigh the weight. Borosilicate glass is generally lightweight. Thick, heavy glass is likely ordinary glass.
3. Check the label. Authentic products will typically have the words "Borosilicate" or "Borosilicate" on the bottom of the cup.
4. Observe the light transmittance. Borosilicate glass generally has a light transmittance of over 90%, making it appear clearer than ordinary glass.
In short, borosilicate glass teacups are a worthwhile investment for their safety, practicality, and aesthetics. They're a great choice for daily use or as gifts. Don't hesitate if you're interested!
